If you have a tiny apartment, zero counter space and only two people to feed, hefty meals are out. This acorn squash with couscous is just the right size.
Cut squash lengthwise in half; remove and discard seeds. Sprinkle squash with salt and pepper; place in a microwave-safe dish, cut side down. Microwave, covered, on high for 10-12 minutes or until tender.
Meanwhile, in a large skillet, heat oil over medium heat. Add onion; cook and stir 5-7 minutes or until tender and lightly browned. Add sausage; cook and stir 2-3 minutes or until lightly browned.
Add stock; bring to a boil. Stir in couscous. Remove from heat; let stand, covered, 5 minutes or until stock is absorbed. Spoon over squash. If desired, top with feta cheese.
